UNITED STATES PATENT OFFICE.

BER'TRAM G. SEEBAGH OF PERU, ILLINOIS.

COMPOSITION FOR CLEANING METALS.

SPECIFICATION forming part of Letters Patent No. 244,937, dated July 26, 1881,

To all whom it may concern.-

Be it known that I, BERTRAM GEORGE SEE- BACH, of Peru, in the county of La Salle and State of Illinois, have invented a new and useful Improvement in Compositions for Oleanin g Metals, and I do hereby declare that the following is afull, clear, and exact description of the same.

My invention relates to an improved composition for cleaning zinc, nickel, brass, copper, or any royal metal, and imparting to the same a fine po1ish; and it consists in the following ingredients and proportions:

First, I take commercial potash and dissolve it in water, one part potash, by weight, to ten parts of water. This solution is filtered, evaporated as dry as possible, then powdered and mixed with an equal weight of fresh lime, (also powdered,) and the mixture then sifted through bolting-cloth No. 13.

Secondly, I take a mineral-oil product, such asis used in makinglubricatingoils, and known as"machine-stock. This is filtered to free it from impurities.

Thirdly, I take an oil obtained from the fruit of Elais guiniensis by expression. This is purified byfirst beating the oil, and when in a liquid state adding one part, by weight, of chalk, to one hundred parts of the oil, to free it from any present acid. It is then maintained at a temperature of 115 Fahrenheit for four hours, I

after which the clear oil is decanted and filtered, so as to free it from any gritty substance Application filed April 18, 1881. (No specimens.)

there may be in the same. Equal parts, by weight, of these two oils, are then mixed together, and a given part, by weight, of this mixture, is added to an equal part, by weight, of the powdered mixture of potash and lime, and the wholethen ground together to the consistency of a-homogeneons paste. This paste I preferably perfume with equal parts of the oils of sassafras and bitter almond; but this is not essential to the cleaning and polishing efl'ect of the compound, and may beomitted.

To use this composition it is only necessary to dip a rag into the same and apply it to the metal by rubbing, and then finish ofi the surface with smooth chamois skin, which will cause the surface to be polished to reflection, giving on zinc-work a particularly fine'efi'ect, and a good finish for all metals.

This composition is not injurious to the metals, and produces afine polish, even on surfaces which are temporarily subjected to high temperatures.

Having thus described my invention, what I claim as new is The composition for cleaning and polishing metals herein described, consisting of potash, lime, mineral oil, and the oil of Elat's gm'niensz's prepared and compounded in the manner and in about the proportions described.
